F snnrranv FIXTURE. Application filed Augii s ti Sieri My inventionrelates principally nals ofthe type where the fixture "ground mithe rearto fit aga nst a wall and which is either hung on the wall or placedagainst the wall and set on the Ifioor and which is ordinarily usedindependently offthe ordithat will be large. enough in area to make itunnecessary to use separate marble stalls and also large enough toprovide an instal lation which will be sanitary in-every way and at thesame time of such design that it can be made of the higher qualities ofvitreous china which are so dense in their body that the body and glazewill harmonize and insure against crazing which is so common with thecoarser fixtures of this type now very largely used.

A large fixture of this type when made of vitreous china has a tendencyto shrink and warp to such an extent that it is unsalable. There arealso strains set up in the shrinkage of a large piece of this type thatmake the hazard of manufacturing during the firing operation extremelyserious, so much so, in fact, that very few manufacturers are willing toattempt to manufacture such a difficult piece.

I have improved the method of manufacture of these fixtures in themanner shown in the accompanying drawings so that we are able tomanufacture these fixtures on a commercial scale without a prohibitiveloss or warpage.

The primary idea of the invention is the provision of triangular tubularcolumns extending the vertical length of the urinal on each side, thussupporting the fixture in such way that it will resist the strainincidental to the firing operation.

The accompanying drawings illustrate the method by which these objectsare obtained. Figure 1 illustrates a front View in perspective of aurinal of this type. Figure 2 illustrates a view in side elevation.Figure 3 shows a top plan view of the same urinal as shown in- Figures 1and 2 indicating in dotted lines the location of the tubular columnswhich are anessential part of this invention.

The construction of the bottom portion of the urinal asindicated at 6 is so designed as to prevent excess Water of any kindsplashing on the floor of the room.

It will be noted in these drawings that longitudinal hollow tubularchambers are formed by the rear or main wall (1), the side walls and theintermediate walls The longitudinal hollow chambers form extremelystrong supporting means which brace the fixture against drying andshrinkage strains and make the firing of the device much more feasiblethan otherwise. The tendency of this fixture during the firingoperation, not provided with these tubular portions, would be for theside walls to shrink inwardly and for the back and side walls of thefixture to warp so that it could not be fit snugly against a wall.

Referring to Figure 5, the bottom of the bath tub (20) is .made integralwith the" ends (21) and the sides (22). This fixture is also providedwith an integral rim (23) and with similar tubular supports along thelength of the fixture, as indicated. at 24.
